The Food and Drug Administration announced Wednesday it’s pushing new voluntary guidelines in the use of drugs on farm animals. The federal agency is trying to curb the use of growth enhancers in livestock.
A Purdue University expert says science has yet to show a link between antibiotics or growth enhancers used in cattle and the emergence of so called “superbugs” in humans.
Professor of Food Animal Production Medicine Dr. Mark Hilton said in a statement that growth enhancers fed to pigs, chickens and cows do not pose a threat to humans, and that overuse of human antibiotics is the more likely cause of superbugs.
“Over use in human medicine is probably just as much or more to account for it,” Hilton said. “But the antibiotics that are used for growth in livestock, few very of those are even absorbed outside of the gastrointestinal system.”
He says the U.S. meat supply is always thoroughly tested and free of antibiotics and is the safest in the world.
